Thanks Mehul!.

Newton couldn`t entirely "leave" Mauser..
I have the book by Bruce M Jennings: "Newton, The father of high velocity"( 1985)...its an extremly important book in a gunbook collection. Newton was really a true pioneer in cartridge development. If we leave out the Lazzaronis, I would claim no new cartridge really appeared after WW1..Charles had been there and done it.
The daughter of Bruce Jennings sold a few of Bruces Newton rifles some 3 years ago on GunsAmerica...wished I had bought just one.
Very fine rifle posted here, honers a great period cartridgedeveloper + a collector of fine tast.
